BLANK FOR NAILS.

SP ION forming part of Letters Fatent No. 339,190, dated April 6,1886.

(No model.)

To all whom it may concern:

Be it known that I, J OI-IN T. Jonas, :1 citi- Z611 of the United States, residing at Iron Mountain, county of Menominee, State of Michigan, have invented or discovered a new and useful Improvement in Blanks for Nails; and I do hereby declare the following to be a full, clear, concise, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which-like letters indicating like parts Figure 1 is a perspective view of my Ill]- proved nail-blank. Fig. 2 is an edge view of the same. Fig. 3 is a perspective view of a nail cut from the blank.

My invention relates to blanks or plates for the manufacture of nails; and it consists in a new and improved form of blank, all as more fully hereinafter described and claimed.

Nails having two tapering or wedge-like sides have heretofore been manufactured by feeding blanks or plates of uniform thickness into a machine having cutters set at an angle to the line of feed of the blank, so as to give to the nail cut therefrom a tapering side; and in order to give to the opposite side of the nail a corresponding taper it has been neces sary after each cut to rotate the blank through an arc of one hundred and eighty degrees, and if it is desired to form transverse ribs or teeth along the tapering sides it has been necessary to form said'ribs or teeth by shaping the cutters so as to form these teeth or ribs while severing the nail from the blank.

The object of inyinvention is to so form the nail plates or blanks that nails having the usual tapering sides and having transverse ribs or teeth formed on said tapering sides may be cut from the blanks or plates without rotating them and without changing the shape of the cutters-that is to say, by the use of plain or straight edge cutters. To this end 1 form, by rolling in suitably-shaped rolls, nail plates or blanks A, which are of the usual. shape and size, but have their two sides a tapering from one edge to the other, as shown, and with the sides a at one edge of the blank beveled, as at b, to form a knife-edge longitudinal of the blank, and I also form a series of two or more longitudinal ribs or teeth, 0, on each side of the blank. This blank is fed into anail-machine which has its knives or cutters, which are plain or straight along their cutting-edge, arranged at right angles to the line of feed of the blank, and the nails are cut off from the blank by a series of parallel cuts, as indicated by dotted linesc in Fig. 1. After the nailhas been severed from the blank it is caught by grippers and headed by a suit-able die, as is usual in the ordinary nail-machine, and there is thus formed a nail having the usual tapering sides and having a series of transverse ribs along said sides.

I claim herein as my invention- A nail plate or blank having tapering sides a, bevels b, to form a longitudinal knife-edge along the thinner edge of the plate, and longitudinal ribs or teeth 0 on each of said sides, as herein shown and described.

In testimony whereof I have hereunto set my hand.

JOHX T. JONES.
